QUILTING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 377,242, dated January31, 1888.

Application filed April 18, 1885. Serial No. 162,094. (No model.)

To all whom it may concern:

Be it known that I, HENRY T. DAVIS, of the city, county, and State ofNew York, have invented a certain new and useful Improvement inSewing-Machine Quilting Attachments, of which the following is a full,clear, and exact description, reference being had to theaccompanyingdrawings, forming part of this specification, and in whichFigure 1 is a perspective view of my improved attachment. Fig. 2 is anenlarged transverse section taken on line 2 2, Fig. 1, the quilt beingremoved. Fig. 3 is an enlarged end View. Figs. 4 and 5 are enlargedperspective views of the roller-clips. Fig. 6 is a section taken on line6 6, Fig. 7. Fig. 7 is a section taken on line 7 7, Fig. 6. Fig. 8 is aperspective view of the spring-bushing. Fig. 9 is a section taken online 9 9, Fig. 1; and Fig. 10 is an enlarged section taken on line 1010, Fig. 1.

My present invention relates to a certain improvement on the attachmentshown and described in patents already issued to me, notably in myUnited States Letters Patent No. 263,487, issued August 28, 1882; andthis invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Referring to the drawings, Arep resents part of the top and head of asewing-machine.

B represents the track of the attachment, supported at its ends by legsB, hinged to it, as shown in Fig. 1. Upon this track bear rollers G,secured to the under side of a bar, 0, to which the end pieces, D, ofthe attachment are made fast.

I, I, and J represent rollers journaled in the end pieces, D, the rollerI being the one the lining of the quilt is rolled upon, the roller Jbeing the one the top of the quilt is rolled upon, and the roller 1being the one the quilt is rolled upon as it is completed. The roller Jalso acts as a tension-roller, as in the patent referred to, as well asa support for the top of the quilt.

I I refer to my United States Letters Patent No. 334,646, dated January19, 1886, for the advantages of having the lining and top of the quiltwound on separate rollers.

L represents the clips on the ends of the rollers I I, that are cast inone piece with the gudgeons L, that are journaled in the end pieces, D,and the ratchet-wheels N are also cast in one piece with the clips towhich they belong. By casting these parts together it reduces the costof the frame, and at the same time adds to its stability. The ratchet onthe roller I is engaged by a push-pawl, O, to control the roller and theratchet on the roller 1 by a pull-pawl, P, for the same purpose.

The ends of the roller J are journaled in spring metallic cylindricalbushings T, (see Figs. 6, 7, and 8,) that act to prevent the roller fromturning too freely, and they fit in elongated sockets U in the endpieces, D, and the roller is adjustable up and down to coinpensate foramount of cloth rolled on the roller by set-screws V, that enter theends of the rollers (see Fig. 6) and fit in slots XV in the backs of thesockets, (see Figs. 1 and 3,) and by tightening these screws, to causethe screws to bear on the sockets, the roller may be made to turn lessfreely should it turn too freely in the bushings.

The operation is as follows: The top of the quilt is all rolled upon thetension-roller and the bottom or lining on the roller I, except enoughof each to reach to the machine-needle. As the quilt is finished androlled upon the roller 1', the top and lining are unrolled and thecot-ton put on as in the attachment shown and described in said UnitedStates Letters Patent No. 334,646.

I claim as my invention 1. In a quilting attachment for sewing-machines,the combination of a suitable support, a longitudinal track-bar, endpieces, a liningroller, a winding'rollcr, a combined cover and tensionroller, and means for imparting tension to the latter roller,substantially as described and shown.

2. A quilting attachment for sewing-machines, consisting of alongitudinal track-bar, end pieces, lining-roller, winding-roller, andcombined cover and tension roller, and springmetal bushings T,surrounding the journals of the cover-roller, substantially as describedand shown.

3. A quilting attachment for sewing-machines, consisting of alongitudinal traclrbar, end pieces, lining-roller, winding-roller,combined cover and tension roller, the elongated sockets V, having slotsW, and the set-screws for adjusting the cover-roller, substantially asdescribed and shown,

4. A quilting attachment for sewing-Inachines, consisting of alongitudinal track-bar, end pieces, a lining-roller, and awindingroller, said rollershaving on each end a clip,

L, formed with a gudgeon, L, and one of the clips on each roller havinga ratchet-whee], N, [o in combination with suitable pawls on the endpieces, substantially as described.
